SPECIFICATION forming am of Letters Patent No. 648,467, dated May' i,1906'.

d Applicationled` April 17,1899. Serial No. 713,409. (No model.)

' declare that the followingis a full, clear, and

exact description of same. l

My invention relates particularly to the art or manufacture of boats,canoes, and the like,

l and has for its .object .to provide a -molded boat and one that willbe more durable than if constructed by building up and joining togetherseparate sections of material, besides being constructed in'less timethan has been possible heretofore. To this end I saturate a fabric,either in one piece or in a number The preferred manner of carrying outmy invention is to saturate a sheet of felted fabric in a solution ofshellac. vThis sheet while wet is applied to anpattern or mold either bylaying it upon or stretching it over the mold,`

and the ends of the sheet are joined together over the bow and sternportions or such ends folded and joined, the shell thus molded thenbeing allowed to dry and trimmed and furnished, as usual, after which itis ready to take the Water. For full comprehensiomhowever, of myinvention-reference must be had to the accompanying drawings, in whichlike symbols indicate the same parts, and where- Figure l is aperspective view of a boat in course of construct-ion upon its mold.Fig. 2 is a rear end view of the lcompleted boat. Fig. 3 is a transversesectional View taken about midway of the length of the boat; and Fig. 4tis a similar view to Fig. 3, but showing the shell upon the mold. l

The pattern b may beof any desired contour and preferably has akeel-strip c, rectangular in cross-section, anda series of strips d ofsmall semicircularcross-section laid upon the portion thereof from whichthe bottom of the boat is molded. The felted fabric e is saturated,preferably, by immersion in shellac, which renders it While wetperfectly pliable lifdesired, be pressed into the interstices be'- tweenthe keel-strip c and the strips d, which are located equidistant apartand on each side of said keel-strip, and betweensaid strips d in orderto impart asuperior finish, yet I have found this quite unnecessary, asthe natural weight of the saturated fabric will cause it to sinkinto allrecesses. The edges of the folded portions of the end f of the sheetthat envelops the bow portion of lthe mold are joined molded isthenallowed to thoroughly dry, the

stretcher-strips 7L are then removed, and the shell, which when dryalthough slightlyl elastic is comparatively rigid, can 'then be re- Amoved from its mold and after `receiving the flooring, seats, andjusualtrimmings is ready to take the Water. I I

I prefer in `heavy boats to allow the keelstrip c and strips d to remainin their places embedded in the felted fabric in order to provide meanswhereby the flooring, foot-rests, and the like may be secured in place,although in light boats or canoes the corrugations formed by the strips7L and keel molded by the keel-strip will impart suliicient rigidity tothe bottom of the craft.

It is obvious that the time expended in stretching the sheet over themold or pattern and forming the joint at eachfend (as the saturation ofthe sheet and drying of the shell require no attention) is all that needbe expended inthe construction of the shell of a boat, canoe, or thelike according to my inventiou. Consequentlyany one of averageintelligence can manufacture avcraft of this nature in about one-tenththe time it has heretofore taken a skilled boat-builder to build ICOhaving-a resinous substance appliedv thereto,`

Substantiallyas described; 'l v onefof the usual type. l It is further`ob'vicus-V .-that if apunt form is desired both ends can be constructedaccording to my descrption'of 7 the constrnction'lof the stern or bothendsn- .iron

Without departing from the spirit vof .my invention. l e

lWhile `I lhave described indetail the fullyconstructed boat, I do netherein claim saine,- as such forms the subject-matter of la separateapplication.
